This series is very crucial for revival of cricket in Pakistan.
PCB is in talks with Bangaldesh as Pakistan is due to host them for 3 T20Is and 2 Tests in Jan/Feb 2020. Pakistan wants to play the entire series in Pakistan and has also proposed a Day/Night Test Match in Karachi. BCB is still awaiting clearance from their government and their loint of view is that they will play only T20s in Pakistan and Tests in neutral venue. Interestingly, Bangladesh U-16 Men and Women's team already toured this year but sadly, the security measures are not the same for men's International team.
PCB is also in talks with South Africa and Ireland for a tour in April or May 2020 as Pakistan's window is completely empty at that time. Ireland Cricket Board's CEO recently visited and he was completely satisfied with the security measures.
PCB is also expecting Afghanistan to tour in 2020. So, good times are going to be finally back for Pakistan
